How to Remove the Governor From a Moped

Moped engines are restricted through various features by the manufacturer.

Moped manufacturers often build in ways to restrict mopeds to reduce their top speed and acceleration. Although companies rarely place an actual restricting "governor" in their mopeds, they do place restrictive air boxes and small carburetor jets that reduce fuel flow to the engine, resulting in loss of moped performance. Maximize your moped's performance by removing these restrictive items on your engine.

Things You'll Need

• Phillips screwdriver
• Electric drill
• Flat-head screwdriver
• Larger jet

Instructions

Drilling into the Air Box

1. Locate your moped's air box, which controls the amount of air that travels into the carburetor. The air box is usually next to the carburetor.

2. Unscrew the Phillips screws holding the air box in place and pull the air box off the moped.

3. Drill three holes into the air box using your electric drill. Make sure the holes are at least 1/2 inch in diameter.

4. Replace the air box and screw in the Phillips screws securing the air box to the engine.

Rejetting Your Carburetor

1. 

   The small metal piece between the pistons is the carburetor.

   Locate your moped's carburetor, a small, silver, metal box that controls the fuel flow into the engine.

2. Remove the carburetor using your flat-head screwdriver. Usually, the carburetor is held in place by a clamp. This clamp can be removed using your flat-head.

3. Strip down the carburetor until all of the pieces are off.

4. Locate the small, golden screw that has a hole in the middle of its head. This is the carburetor's jet, which controls the fuel flow into the engine.

5. Replace this jet with a larger one that will place more fuel into the engine.
